I got mine off of ebay, needed one that was cheap and had measurements for movie cameras and this one came up. It's alright, though my main problem with it now is that it's very difficult to get a reading in the bright light. Not because it's insensitive, but because you can't see the LED that tells you to stop turning the wheel. I do large format photography as well, and for that I use a Pentax V spot meter.
